Mixed mammary
tumors and mammary sarcomas are rare, and sarcomas appear to be low
metastasize. Feline mammary complex carcinoma and adenocarcinoma are one of the
most common feline neoplasms and represent an important cause of mortality. It
is caused at all age’s stage of feline, canine and all types of animal and
human beings. There are two main types of tumors, benign and malignant. A
malignant mammary tumor is very quickly spread to lateral region of lymph
nodes, and sites of local metastases are dictated by lymphatic drainage
patterns. The malignant tumor rapidly spread in thoracic mammary gland (cranial
and caudal gland), malignant tumor is also known as cancer. Cancer is a groupof diseases involving abnormal cell growth with the potential spread to otherportion of the body. Benign tumors do not spread to other body portion, and
this all tumors are not a cancerous. Mostly the feline mammary tumors are
malignant tumors, the ratio or percentage of malignant mammary tumours is
higher in cat (86%) as compared to dog (42%) and the histology of feline
mammary tumors is closer to that in human breast cancer.
Although
there are many kinds of cancer, all cancers start because abnormal cells grow
out of control. There are so many different types and different stage of cancercan be having very differently. For example, Breast cancer, lung cancer and
skin cancer are very different diseases. They grow at different rates and respond
to different treatments.
